RAID setup suggestions needed

I have 2 ideas for a RAID setup and would like some input.

Setup ONE - Two 20 gig HDs partitioned 5/15, mirrored. OS and progs will reside on 5 gig partition with data storage on 15 gig partition.

Setup TWO - Two 20 gig HDs mirrored, single partition. Third HD (4 gig) for OS and progs. All data storage will be on the mirrored drives. A ghost image of the 4 gig drive will also be stored on the mirrored drives.

Does setup TWO offer any SAFETY benefits over setup ONE - protection from viruses, worms etc? I think setup TWO might be faster, but I'm more concerned with safety.

Any/all comments appreciated. Thanks.
 
Mirroring (RAID 1) is not faster, but it is fault tolerant. RAID 0 is not fault tolerant, but faster. Both can be used together in a HARDWARE array, but not a software array.

To use both RAID 0, 1 together in a hardware array, you need a total of 4 drives with 4 IDE channels to make two independent RAID 0 arrays. One array then mirrors the other.
 
From a virus/worm protection, RAID offers 0 protection. As soon as the worm writes to the primary drive, it also gets written to the backup drive.

I'm assuming you're using IDE RAID, in which case you may want to test scenario 2. Make sure that the data drive(s) are recoverable after you reinstall the OS to its drive.
